Videos/Podcasts/Articles

Home performance articles and stories from the field with internationally respected building forensics guru Corbett Lunsford at the Building Performance Workshop. Hear new episodes of the Building Performance Podcast, see new videos from the Home Performance YouTube channel, and learn all about how diagnostic testing (more than an 'Energy Audit') can make home improvement and new home construction a proven process!

Corbett gives a crash course in the TEC’s DG-1000 used with Minneapolis Blower Door equipment (including the Duct Blaster, TruFlow Plate, and Exhaust Fan Flow Meter). TEC took away a few features like Equivalent Leakage Area estimation, but added the Tubing Assistant and firmware updating, which could endlessly add features based on user feedback.

Even when you build a perfectly performing house, your client may feel like the house is exacerbating sickness. Know that a huge part of home performance contracting is knowing your way around psychology and adult education- express yourself with performance testing data AND with listening and emotional connection.

Home Diagnosis co-host Corbett Lunsford illustrates the basics of control over indoor air quality and indoor chemistry in the second video collaboration with Healthy Indoors Magazine. Informed by all we're learning from the HOMEChem Experiment. Learn more at:

Corbett and Kristof Irwin from Positive Energy Austin dive deep into the revolution that's brewing. Building Science will never be the same after the HOMEChem Experiment shows us the 4-dimensional chess game that's happening at a molecular level inside every building and vehicle in the world.

Chlorine is an ingredient in bleach, which many people use to clean surfaces, dishes, and clothing at home. Turns out, it's not as clean as we thought- learn how to control your HOMEChem by knowing what happens when chrlorine in bleach reacts with the stuff indoors, and what it might be doing to your family.

Once ozone bonds with anything in your living space, it has a very bad baby- Hydroxyl Radical (OH). This sweaty, groping molecule is the drunken fratboy (with cargo shorts around his ankles) of the HOMEChem world. Featuring HOMEChem scientists Marina Vance, Delphine Farmer, and Charlie Weschler.

Indoor Air Quality is being explored at breakneck speed with the HOMEChem Experiment, and not surprisingly, ozone (O3) is proving to be the original villain in the complex system of interactions that make the air we breathe much more worrisome than anyone guessed. Featuring HOMEChem scientists Marina Vance, Delphine Farmer, Charlie Weschler, and Richard Corsi.

Charlie Weschler sits down with Grace and Corbett and gives fascinating examples of the complexity of indoor air chemistry. He is an air quality legend, a professor on 3 continents, and one of the nicest guys you'll ever meet. More at: http://HomeDiagnosis.tv/homechem

Ventilation is simple in concept- it moves bad air out and good air in. But the applications can be intensely confusing- Grace and Corbett help peel the onion of controlling home performance dynamics (and the HOMEChem issues we're learning more and more about) using fans and controls available around the world.
